Of course, provided you release your code under BSD license, and that
you know it's your code, untainted :). If there's FreeBSD code, it's
not a problem as long as you also add the relevant license and copyright
sections as-is, along with your own if you did modifications). Ideas and
concepts are not code (as someone mentionned, a process can be patented,
but that's really another story).

It is common for NetBSD to borrow nice ideas from other systems, such as
SunOS, (i.e. kernel module loading API and kvm(3)), of course they were
re-implemented however, it was done to maintain a similar API to that of
another popular operating system for convenience in this case. So why
